In a new study a decreased survival was found in glioblastoma patients with long-term use of mobile and cordless phones. The study is free to download here.

According to the study use of wireless phones in the >20 years latency group (time since first use) yielded an increased hazard ratio (HR) = 1.7, 95% confidence interval (CI) = 1.2–2.3 for glioma, a decreased survival. For astrocytoma grade IV (glioblastoma multiforme; n = 926) mobile phone use yielded HR = 2.0, 95% CI = 1.4–2.9 and cordless phone use HR = 3.4, 95% CI = 1.04–11 in the same latency category. Due to the relationship with survival the classification of IARC (possibly carcinogenic to humans, Group 2B) is strengthened and RF-EMF should be regarded as human carcinogen requiring urgent revision of current exposure guidelines. The findings are discussed in detail in the article.
